Air-oxygen mixing burner in the pan furnace

摘要

A melting device comprises a burner arrangement (8) with a plurality of burners (12, 13, 14) arranged on a side wall (9) of a melting tank (2), from which fuel gases are applied to the material (5) to be melted at a predetermined angle that form several zones of different heat input. Flame-free burners and / or air / oxygen mixing burners (12, 13, 14) are preferably used, in which the proportion of oxygen in the supplied oxidizing agent can be regulated as a function of parameters measured in the melting tank (2). The device according to the invention is particularly suitable for the production of ceramic frits and is characterized by a high level of economy and low NOx values in the exhaust gas.
